COIL BOX.

Original application filed March 24, 1923, Serial No. 627,252. Dividedand this application filed October T 0 all '10 7mm m at! concern Be itknown that l, Fnnonron NILLIAM Knarrarnmn, a citizen of the UnitedStates, residing at Ponds, in the county of $t. Louis and State ofllllissouri, have invented certain new and useful Improvements in CoilBones, of which the fol owing is a specification.

This invention relates to ignition systems and is a division of thematter shown in my application #627,252, filed March 24, 1923 andrelates especially to a box or container for induction coils.

The principal object of the invention is to provide an improved box orcontainer from which, by reason of the specific construction of thecontainer, the induction coil may be removed with as little disturbanceof the wires as possible.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and:

In the accompanying crawings forming part of this specification, inwhich like numbers of reference denote like parts whereever they occur,

Figure 1 is a plan view of the coil box.

Figure 2 is a side view of the same, with parts broken away to show avertical central section.

Figure 3 is a front view of the coil box; and

Figure l is a bottom view of the same.

This box or container is indicated in general by the numeral 1 and thecoil contained therein at 2, which may, as designed have a wooden casing3. The box itself comprises a sheet metal structure having a bacir wall5 from which project securing lugs lei having screw openings 15 thereinfor the reception of screws for holding the box to the instrument boardof an automobile. These lugs project from the lateral edges of the rearSerial No. 686,717.

wall and from the same rear wall project forwardly the side walls 4,having their forward edges turned inwardly to form spaced flanges 9 soas to provide a wide slot l be tween them. at 6 is shown a bottom whichextends forwardly from the lower edge of the back wall 5 and has sideedges flush with the side walls, said bottom having a cen trallydisposed opening 7 to receive the bottom connection or binding post 8 ofthe coil. Rested on the bottom is an insulating plate having an opening12 through which the binding post 8 projects, the bottom 11 of the coil.resting on this insulating plate. It will be noted that the lugs 14: arepreferably ex tensions of bars 13 which are fixed to the back wall. At16 is a removable cover consisting of a top 17, side walls 18', a rearwall 19, and front wall 20, the latter having a thumb piece 21 to aid inits removal.

llt will be seen that the coil has the usual connections 22 and 23 whichslide in the slot 1 With this construction it is easy to see that uponremoval of the cover and disconnection of the bottom wire the coil withits connection to the binding posts 22 and 523 may he slid upwardly outof the container.

Having thus described the invention, what claimed as new, is: Acontainer for ignition coils consisting of a sheet metal structurehaving a back wall provided on its lateral edges with securing lugs,side walls extending forwardly from said lateral edges and having theirforward edges turned inwardly toward each other to form spaced flangesand providing a slot between said flanges, a bottom extending forwardlyfrom the lower edge of said bacl: wall and having side edges flush withsaid side walls, said bottom ha ing a centrally disposed opening toreceive the bottom connection of an ignition coil, the slot accommwdating the side connections of said coil, and a removable top fittingsaid back, sides and flanges at their upper edges.

in testimony whereof I heretunto atlix my signature.
